Need fire stopping in Tealing?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What the job involves on each surface

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.

About our fire stopping in Tealing

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows, and what we’re called in for most is seals that don’t match their tested detail and fire-rated sealant that has cracked or shrunk back. For commercial sealant work in Tealing, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In smaller Scottish places like Tealing, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Quoting for work in Tealing

These are the things that shape the price:

  • Travel to remote or island sites
  • Working within restricted access windows
  • Backing rod, priming and other preparation
  • Removal of failed or old sealant

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • The site address and postcode
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back
  • The product your specification calls for

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call 01277 525 020 or email drawings and photos.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Compartment walls and floors in Tealing

Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, with proprietary products, intumescent ones included, tested for their end use. We install fire-rated sealant to that tested detail where it is specified.

For a building such as Tealing Parish Church And Churchyard, new heating or data runs are the usual reason penetrations need sealing. Large healthcare estates like Maryfield Hospital (4.2 miles south of Tealing) change their services often, so penetration seals are worth checking after M&E work.

Tealing is about 4 miles north of Dundee, in Angus. Commercial clients in Tealing use us for work on service penetrations. Across Angus, 65 places are covered, Tealing among them.

We also cover Inveraldie (1 mile south-east), Barns of Claverhouse (2 miles south), Strathmartine (3 miles south-west), Bridgefoot (3 miles south-west) and Claverhouse (3 miles south) for service penetrations. Further afield, our area takes in Arbroath (14 miles east), Forfar (8 miles north), Monifieth (6 miles south-east), Carnoustie (10 miles east), Kirriemuir (10 miles north) and Hunter's Town (9 miles east).

Signs you need fire stopping in Tealing

Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access typically bring them to light.

Things that typically lead to an enquiry:

  • Hidden openings found during inspections
  • Open linear gaps along the top of fire-resisting walls
  • Penetration schedules that need working through
  • Seals that don’t match their tested detail

Where a unit on an estate such as Claverhouse Industrial Park, which lies south of Tealing, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

What to look for in a quote

  • What the guarantee covers, and for how long
  • What level of public liability insurance do they hold?
  • Health and safety accreditation such as CHAS
  • Will failed sealant be removed rather than covered?

Choosing a commercial sealant contractor

FAQs: Tealing

Which Scottish guidance covers penetration seals in Tealing?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Is Tealing too far out for you?

No. Small places get the same service as large ones. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months.

How a job runs

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Tell us who will meet us and how to get in at your building near Tealing. We will confirm the plan with the fixed quote.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached
  • Tell staff and tenants when we will be in

Why deal with it now?

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Resealing early avoids that.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
